masterkey has a critical bug needs to be fixed ASAP

masterkey has a critical bug that allows SWS10 and LCMG to one shot people at any range because any pellet of masterkey gets full damage from main rifle (75 for SWS10). So you can one shot crowds up to 100 meters with shotgun spread and no aim at a crazy rate and you can kill planes/tanks with masterkey using AP ammo.
